The Honest Dog
When you get a dog, whether a puppy or full-grown adult, you get a living, breathing, thinking, loving animal that looks to you for support and care. You have a relationship with this being, a responsibility for this animal, much as it would be if you had a child.
In today's world, this animal can go with you many places and share your life in so many ways that our grandparents cannot imagine. Dogs are part of our lives and will remain so forevermore.
We'll spend thousands of dollars on them over their lifetime. We'll make sure they get the best medical care. We'll train them and teach them to be the best companion they can be.
Much as it would be if you had a child.
The point I'm making: Do NOT get a dog with the idea that you can return it, can get rid of it, can give it away to somebody else "if things don't work out". If you can't make a commitment to another living being, don't get it.
Imagine what it would have been like if your mom and dad decided they didn't want you anymore when you were 2 or 3 or 5 years old and left you with total strangers, and walked away. You are intelligent enough to know there's a lifetime of misery right there.
Much as the dog is intelligent enough to know when it's been kicked to the curb.
Don't do it. Don't get a dog unless you are ready for the loving lifetime commitment. They don't live that long, really - and they deserve to live a life well-lived and well-loved, just as much as you do.
